Established in 1973, our diesel repair and performance truck products shop has grown from a tiny, one-man show into a thriving national operation. In the early 70s, Val Leefers discovered his passion and talent for innovative diesel performance upgrades that improve fuel injection systems and repairing diesel pumps. After honing his diesel repair skills, Val built a small building just outside Carlinville, Illinois; bought $1300 in inventory; and hung out his shingle. Area Diesel Service was open for business, though business wasnt exactly booming. Val sweated out the rough early years the only way he was fit - by establishing innovative diesel performance that saves customers money over the long haul and by providing dedicated, honest service. Remaining true to those core values to this day, Area Diesel has earned its place as a leader in the Midwest diesel market and later looked to expand on that success. As Area Diesel Service solidified our reputation for providing innovative diesel performance through quality parts and service, both our building and our team began to grow. The Carlinville diesel repair shop has continually expanded to accommodate our passion for innovation. Today, the building boasts extensive space and the latest performance truck products and equipment for our diesel fuel injection department, turbo department, warehouse, and state-of-the-art machine shop - for custom updates and repairs on intricate diesel engines and components. In 1984, we opened a second location outside of Des Moines, Iowa, letting our team serve diesel owners west of the Mississippi. The Iowa branch underwent an expansive overhaul, equipping our experts with all they need for diesel repair and performance upgrades on nearly any diesel engine. In early 2017, we opened our third location in Indianapolis, Indiana, giving our customers on the eastern fringe of the Midwest an opportunity to experience Area Diesels quality products and customer service in person. Area Diesel now has upward of 50 full-time employees, including factory trained diesel technicians. Collectively, we still honor the principles Val built the company on - dedication to improving diesel performance through hard work, honesty, ongoing development of technical skills, and quality diesel performance products. And we cannot forget one of Vals most valued rules: Always go the extra distance to ensure customer satisfaction!
